The Nest Learning Thermostat is some of the latest and greatest technology the HVAC industry has seen in years. It automatically sets your home temperature to your preference by remembering your day to night, week to week and seasonal patterns. This self-learning thermostat system is energy saving, efficient and easy to use.
If you’re considering installing one in your home, the first question you need to ask is if your HVAC system is compatible. The Nest Thermostat is compatible with the majority of low-voltage, 24-volt systems but has a few exceptions, including incompatibility with line voltage, millivolt systems and a few others that might lead to problems with your Nest.
Remote Sensor Thermostats
Not to be confused with remote control systems, wired remote sensor systems receive indoor temperature and outdoor weather information from sensors throughout your home. Although some remote sensor thermostats are compatible with Nest Thermostats, their sensor wires are not. The Nest Thermostat receives its necessary information using Wi-Fi and your home’s location.
Microcontroller Based Systems
A microcontroller unit serves as a mini-computer that governs an integrated circuit or system such as an HVAC. Systems like these that don’t use relays can lead to power sharing issues. Some microcontroller systems could be compatible, but those that aren’t will need to use a common wire.
High Impedance Systems
Hi-Z, or high impedance systems, produce a low current with the possibility of high voltage. Due to the low currents in their wires, these HVAC systems are unable to provide a Nest Learning Thermostat with enough power. These systems can also sometimes be corrected with the use of a common wire.
Proprietary systems communicate with HVAC systems through a serial communications protocol, which The Nest Learning Thermostat is unable to communicate with. However, compatibility is sometimes possible if these systems are wired with standard HVAC wiring.
Other types of wiring and certain types of hardware are also incompatible with the Nest Thermostat. Here at Champion AC, we are Nest Pros! Contact us to see if your system is compatible.
